I am MT: Card Battle has been in the App Store for only a week and already broke into the top 10 paid games. Well, after the successful sales of the game, it's now free-to-play. Those who already purchased the game will receive $5 dollars worth of runes, which is enough to purchase a premium card.

Locojoy's marketing manager, Adam Tesluk, said in a press release that “We really had no idea what kind of demand there would be for I am MT: Card Battle in the United States. We went with a paid app at launch to be sure we could cover our costs,” Adam Tesluk, Marketing Manager, Locojoy said. “After we saw the huge number of gamers willing to purchase the game we knew there are enough U.S. gamers to make free-to-play work.”
